Teflon objects (orange cylinders) were placed in a waveguide with a rectangular cross-section. Then, an electromagnetic signal (blue wavefront) was injected from the right to extract information about ...

So far, the team has measured several effects, including wave steepening, shock fronts and solitary wave fission thanks to the chip. While these nonlinear behaviours had been predicted in superfluids, ...

Until recently, gravitational waves could have been a figment of Einstein’s imagination. Before they were detected, these ripples in spacetime existed only in the physicist’s general theory of ...

Researchers at the LIGO gravitational wave observatory used a new technique called frequency-dependent squeezing to boost weak signals above quantum noise. When you purchase through links on our site, ...

What if the next new theory of the universe didn’t come from a human mind, but from an artificial one? In a development that has left the scientific community both awestruck and unsettled, artificial ...

Researchers have directly observed torsional Alfvén waves twisting through the Sun’s corona — magnetic waves first predicted over 80 years ago. Captured using the Daniel K. Inouye Solar Telescope, ...
